What is Dependency Injection in ASP.NET Core?

Dependency Injection in ASP.NET Core is a design pattern used to inject dependencies (i.e., objects or services) into a class, making the class more modular, maintainable, and testable. This pattern allows classes to receive their dependencies from an external source rather than creating them directly.

In ASP.NET Core, dependency injection is implemented through the built-in IoC (Inversion of Control) container, which manages the dependencies and injects them into classes at runtime. The ConfigureServices method in the Startup class is used to register the services and dependencies that can be injected throughout the application.

The key benefits of using dependency injection in ASP.NET Core include improved code maintainability, testability, and flexibility, as well as reduced coupling between components.

In summary, dependency injection is a crucial concept in ASP.NET Core that promotes effective software design and development practices by simplifying the management of dependencies and promoting decoupling between components.
